This must surely be the world's best known trick coin. Now precisely manufactured by Future Magic! Innumerable routines and effects are possible. A few examples:
A five-cent coin and a fifty-cent coin are put into the hand of a lady in the audience, and she closes her hand. When she opens her hand, the five-cent piece has disappeared, the fifty-cent piece can be shown from both sides, no signs of preparation can be seen. The five-cent piece reappears in your hand, i.e. it has wandered from the lady's hand to your own.

Coin through table - A five-cent and a fifty-cent piece are on the table, covered by an upturned glass. The five-cent piece thus enclosed magically goes through the table top and falls into the magician's hand. The 50-cent piece is still on the table and can be shown without any tricks from both sides when the glass is lifted.

What we consider the most amazing effect - coin through glass: A five-cent piece and a fifty-cent piece are put into a wine glass which the magician holds by the base. The glass is shaken slightly and the five-cent piece, in full view of the audience, disappears, penetrates the stem of the glass and falls from the base of the glass on to the table!!!!!
Incredible effects which can be performed without a lot of practice, because the ingenious trick coin does it all for you.
